Equitable conversion is a doctrine of the law of real property under which a purchaser of real property becomes the equitable owner of title to the property at the time he/she signs a contract binding him/her to purchase the land at a later date. The seller retains legal title of the property prior to the date of conveyance, but this land interest is considered personal property (a right to the payment of money, rather than a right to the property). The risk of loss is then transferred to the buyer – if a house on the property burns down after the contract has been signed, but before the deed is conveyed, the buyer will nevertheless have to pay the agreed-upon purchase price for the land unless the seller in possession or deemed in possession has failed to protect it. Such issues can and should be avoided by parties by stipulating in the contract who will bear the loss in such occurrences. The above rule varies by jurisdiction, but is the general rule.

An action to quiet title is a lawsuit brought in a court having jurisdiction over property disputes, in order to establish a party's title to real property, or personal property having a title, of against anyone and everyone, and thus "quiet" any challenges or claims to the title.

This legal action is "brought to remove a cloud on the title" so that plaintiff and those in privity with them may forever be free of claims against the property. The action to quiet title resembles other forms of "preventive adjudication," such as the declaratory judgment.

This genre of lawsuit is also sometimes called either a try title, trespass to try title, or ejectment action "to recover possession of land wrongfully occupied by a defendant." However, there are slight differences. In an ejectment action, it is typically done to remove a tenant or lessee in an eviction action, or an eviction after a foreclosure. Nonetheless, in some states, all terms are used synonymously.

Escheat is a common law doctrine that transfers the real property of a person who has died without heirs to the crown or state. It serves to ensure that property is not left in "limbo" without recognized ownership. It originally applied to a number of situations where a legal interest in land was destroyed by operation of law, so that the ownership of the land reverted to the immediately superior feudal lord.
